To prevent accidental damage to internal shielding and primary insulation during manufacturing.
12 related patents designed.Prevent the introduction of external impurities between the main insulation layer and the inner shield, as well as the outer shield.
The internal and external shielding is closely combined with the main insulation layer, which improves the performance of partial discharge resistance and in the fight aganist wear.
The insulation material is made of high quality ethylene propylene diene diene rubber (EPDM), which not only has excellent electrical insulation performance and corona resistance, but also has aging resistance and corrosion resistance.
EPDM (ethylene propylene diene ternary rubber) adding with a variety of compounding agents, after being thoroughly mixed, extruded on a tubular conductor, and then heated and vulcanized.
